Loïc Faugeron has posted another article in his "Ultimate Developer Guide to Symfony" series today. In this new article he shares an API example making use of the knowledge gained from the other articles to create a simple project.

In this guide we've explored the main standalone libraries (also known as "Components") provided by Symfony to help us build applications: HTTP Kernel and HTTP Foundation, Event Dispatcher, Routing and YAML, Dependency Injection and Console.

We've also seen how HttpKernel enabled reusable code with Bundles, and the different ways to organize our application tree directory. In this article, we're going to put all this knowledge in practice by creating a "fortune" project with an endpoint that allows us to submit new fortunes.

He starts by creating the project (via Composer's create-project command), sets up a basic routing configuration and installs PHPUnit for testing. He then shows the creation of the controller - test first - to handle the "fortune" endpoint requests. He then comes back in and adds in some logic around the submission including matching tests. This is then refactored further to use Doctrine to insert the contents into a database. Additional code is provided showing how to "wire it all together" and create the database structure. The entire post takes the TDD approach so tests for all submission functionality are included.
